Summoner needs to specialize in Aoe Bursts since DoT is useless in a game like this unless it's a secondary role like in the case of a Scholar. Enkindle's cool down should be reduced to 2min and the cool down should be tied to the pet instead of being a global cool down. Energy Drain shouldn't consume Aetherflow stacks. Summoner should be based on the Elementalist/Shaman in order to resemble the classic image of the Final Fantasy Summoner rather than a Necromancer.
